|Castillo de San Luis in Estepona old town|
There is little left to see of the great castle which once stood at the heart of Estepona, and what remains is not now readily apparent, but it is possible to trace the ruins around the high ground. Its construction followed the seizing of the town in 1457 by Enrique IV. He also built new defensive towers along the coast, since, although they had been expelled from Estepona and their domination of the Peninsula was effectively over, the Arabs - mainly Berbers - were still perceived a problem. Pirate raids were not uncommon and if not wildly destructive, at least a great irritant.
Look out for the Gastro Mercardo San Luis which was the Mercado de Abastos (indoor market) where a section of floor has been opened up to reveal foundations of a rectangular Moorish watchtower in the south east corner of a rectangular defensive construction which predates the castle. In Calle Villa oposite the entrance to the market can also be seen the octagonal foundations of a two storey Roman Mausoleum dated to 4th century AD.
Next to the market is Plaza Casa Cañada, where a small garden has been laid out beneath the Castle walls for visitors to rest among the flowers or drink from the fountain. The existing walls probably date from the 16th century, though they may incorporate some earlier stonework, possibly Moorish.
You can walk around the remaining section of castle wall that remains, Walk down the little path in semi tropical gardens between the market and the castle wall, down the steps into Calle Castillo to view the other side of the castle wall. This wall is actually a double wall fortification. you can return to where you stared by climbing the steps.
The castle is visible from Calle Castillo as a number of town houses that had been built infront of it were demolished in 2014.
Whilst in this area of Plaza Agusto Suarez visit the 'Old Town Hall' which is now an archeology museum.
